Answer:
Regular polygon with interior angle = 156 deg.
It has each exterior angle = 180–156 = 24 deg.
No. of sides in regular polygon = 360/24 = 15.
No. of vertices = 15.
Sum of the interior angles = (15–2)*180 = 13*180 = 2340 deg.
No. of diagonals = 15*(15–3)/2 = 15*6 = 90.
No. of triangles = 13.
No. of isosceles triangles = 15.
Diameter of inscribed circle = s*cot (180/15) = 4.704630109 s, (where s is the side)
Diameter of circumscribed circle = s*cosec (180/15) = 4.809734345 s,
